SPECIFICATION forming part of Letters Patent No. 619,033, dated February7, 1899.

Application filed October 27, 1897. Serial No. 656,527. (No model.)

To all whom it may concern.-

Be it known that we, HUBBARD D. B. WIL- LIAMS and CARL GRUENINGER,citizens of the United States, residing at Mansfield, in the county ofRichland and State of Ohio, have invented certain new and usefulImprovements in a Combined Submerged Lifting and Force Pump; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

Our invention relates to improvements in combined submerged lifting andforce pumps; and the objects of our invention are, first, to provide apump which will lift the water at the upward stroke of the piston intothe discharge-pipe and at the downward stroke of the piston to force theWater in the lower part of the pump-barrel upward through a tubularpiston-rod and discharge the same into the discharge-pipe; second, to soconstruct and arrange the stuffing-box formed in the upper end of thepump that the packing surrounding the piston-rod can be adjusted withoutremoving the pump from the well or detaching the discharge-pipe, and,third, to make a cheap, durable, and efficient means for the purposestated. We accomplish these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a longitudinal sectionalview of our improved combined submerged lifting and force pump, showingthe construction and general arrangements of the parts. Fig. 2 is anenlarged view of the pump-cap in section, 40 showing each part detached,also showing the tubular piston rod cap for the same and check-valve andstuffing-box and mode of adjusting the same. Fig.3 is a transversesectional view of a portion of the cap, taken in line a: m, Fig. 2,showing the discharge-ports. Fig. 4 is a view showing more fully theconstruction of the tubular piston-rod cap, also showing a portion ofthe tubular piston-rod secured in the lower end of the cap, also show-50 ing stuffing-box surrounding the piston-rod and general constructionof the same. Fig.

5 is an enlarged view of piston, tubular piston-rod, a portion ofpump-barrel, and lower inlet-valve, showing the full construction of allthe parts.

Similar letters and numerals of reference in dicate the parts throughoutthe several views.

In the accompanying drawings, Aindicates the pump-barrel or cylinder.

B is a cap forming the bottom of the barrel. The said cap isscrew-threaded upon the inside and is screwed upon the lower end of thepump-barrel. The said cap is provided with the inlet-port O and valve D.The up per end of the barrel is provided with the cap E. The said cap ismade in three parts-1, 2, and 3. The part 1 is made larger in diameterthan the pump-barrel and is provided with the downwardly-proj ectin gsleeve F, threaded upon the outside and screwed Within the upperend ofthe pump-barrel. The upper end is provided upon the inside with thethreads G, which conform to the threads H formed upon the outside of thesleeve forming the center portion of the cap, (marked 2.) The bottom Iof the part marked 1 is provided with a number of inlet-ports J on aline with the outer diameter of the pump-barrel. These ports form thepassage for the water to supply the upper portion of the barrel K. Acheckvalve L is placed within the cap closing the ports J. The saidvalve has an opening through the center the full diameter of the sleeveF. The bottom M, forming the center part 2, is also provided with portsN, checkvalve 0, upwardly-projecting sleeve P, and stuffing-box Q. Theupper portion (marked 3) screws within the center portion 2. The top maybe flat or crowned, as shown, and provided upon the top with the sleeveR, threaded upon the inside and in which is secured the discharge-pipeS.

We have shown in Figs. 1 and 5 two differently-constructed pistons tooperate in conjunction with a hollow or tubular piston-rod. The oneshown in Fig. 1 we will first describe.

T indicates a piston, which is composed of the head U, secured rigidlyupon the tubular piston-rod V. The said head is provided with acup-shaped leather valve W. The said valve is secured to the head by themetal washer X and held by the screws or a. Y is a metalsleeve providedwith the flange Z in diameter the size of the inside of the pump-barrel.The said flange is provided with suitable pack ing A to impinge theinner wall of the barrel. This portion of the piston is loose upon thetubular piston-rod. A cap B is screwed within the lower end of thepiston-rod, and ports C1 are made through the piston-rod for thedischarge of the Water in the cylinder at the downward stroke of thepiston.

In Fig. I we have shown the piston in position when in its downwardmovement, the water passing through the ports 0 up through the tubularpiston-rod through the ports D into the discharge-pipe S. It will bereadily seen by those skilled in the art that when the piston is movingdownwardly the check-valve L rises, allowing the water to enter theports J, supplying the upper portion of the cylinder. A reverse movementof the piston raises the valve D, the lower portion of the pistonremaining stationary until the cap B comes in contact with the flange Z,the valve L closes, and the pressure of the water opens the valve 0,forcing the water through the ports N into the discharge-pipe S.

The piston, as shown in Fig. 5, is composed of the head E having anupwardly-projecting sleeve F in which is secured the tubular piston-rodV. A downwardly projecting sleeve G is formed upon the under side of thehead and is threaded upon the outside. Two cup-shaped leather valves Hand I are placed upon the sleeve, a metal washer J placed between thetwo leather valves, and a nut K clamps the valves and washer rigidly tothe piston-head. The upper end of the tubular piston-rod is shown inFigs. 2 and 4. It is provided with a hollow slotted cap L The said capis composed of two parts 4: and 5. The lower portion 5 is screwed uponthe upper end of the tubular piston-rod. The part 4: is attached to thepart 5 by threadsmale and female. A check-valve M is placed within thehollow cap L which closes the upper end of the tubular piston-rod whenthe piston is in its upward movement and opens when the piston is in itsdownward movement. The object of the said check-valve is to prevent theWater in the dischargepipe from filling the lower portion of thecylinder when the piston is discharging the water from the upper portionof the cylinder. The gland or stuffing-box Q is provided with a notch None upon each side. The lower end of the cap L is also provided withdownwardlyprojecting lugs 0 which mesh into the notches N The object ofthe lugs and notches are for the purpose of compressing the packing atany time should it become worn from use without removing the pump fromthe well. It will be readily seen that when the connecting-rod P isdetached from the pump-handle it can be rotated, turning the cap Ltubular piston-rod, and piston. The piston is forced downward in thebarrel until the lugs 0 pass into the notches N By turning theconnecting-rod to the right turns also the gland Q, compressing thepacking within the stuffing-box.

Having fully described our invention, What we claim as new, and desireto secure by Letters Patent, is-

1. Ina double-actin g submerged lifting and force pump, the combinationwith the barrel having its lower and upper ends screw-threaded andhaving valve-controlled caps secured thereon, of a hollow piston-rodhaving inlet and outlet openings therein and having a piston upon itslower end consisting of the rigid cup-shaped head, the movable sleevehaving the flange with the packing-ring upon its outer edge adapted tocontact the side of the pump-barrel, and a cap secured in the lower endof the piston-rod to limit the movement of the movable sleeve upon thepistonrod.

2. In a double-acting pump, the combination with the barrel having itsupper and lower ends screw-threaded, a sectional cap secured upon theupper end and having Valves within two of the sections, of a hollowpistonrod provided with the slotted cap, a valve in said cap to closethe top of the piston-rod, and a piston-head at the bottom of the rodconsisting of the rigid cup-shaped head, the movable sleeve having theflange with a groove in which fits a packing-ring, and a cap secured onthe end of the rod to. limit the movement of the flanged sleeve.

In testimony whereof We aflix our signatures in presence of twowitnesses.
